From f74cf04d3e81728591999b8ca952313178c54824 Mon Sep 17 00:00:00 2001 From: Dylan Baker Date: Wed, 28 Feb 2018 10:13:38 -0800 Subject: meson: Allow building dri based EGL without GLX It should be possible to build EGL without GLX, but the meson build currently doesn't allow that because it too tightly couples glx and dri. This patch eases dri and glx apart, so that EGL without GLX can be built.
